TECNA TE553 Resistance Welding Controls

Microprocessor-based welding control unit for resistance welders FOR SALE at TECNADirect.com

TECNA TE553 is a microprocessor-based welding control unit for resistance welders. The task of the welding control unit is to manage the welder components, in particular the controlled diodes that carry out the welding current adjustment.

The TECNA TE553 is a particularly versatile welding control unit as it may be adjusted to different types of welders; it may be installed not only on spot and projection welders but on seam welders too. Moreover, it may work with power adjustment: both in constant current and in constant energy (optional). The number of inlets and outlets may be increased so to better adjust the welding control unit to  automatic machines. It is possible to store up to 250 different welding programs, 31 of which are recalled directly from an external device. Each program comprises several programmable parameters that describe the work cycle. In addition to the plain 4-stage welding cycle, the control unit allows the running of  elding processes with pre-welding current, post-welding current, slope and pulses.
